Implementation of a Wireless ECG Acquisition SoC for IEEE 802.15.4 (ZigBee) Applications

Abstract

This paper presents a wireless biosignal acquisition system-on-a-chip (WBSA-SoC) specialized for electrocardiogram (ECG) monitoring. The proposed system consists of three subsystems, namely, 1) the ECG acquisition node, 2) the protocol for standard IEEE 802.15.4 ZigBee system, and 3) the RF transmitter circuits. The ZigBee protocol is adopted for wireless communication to achieve high integration, applicability, and portability. A fully integrated CMOS RF front end containing a quadrature voltage-controlled oscillator and a 2.4-GHz low-IF (i.e., zero-IF) transmitter is employed to transmit ECG signals through wireless communication. The low-power WBSA-SoC is implemented by the TSMC 0.18-μm standard CMOS process. An ARM-based displayer with FPGA demodulation and an RF receiver with analog-to-digital mixed-mode circuits are constructed as verification platform to demonstrate the wireless ECG acquisition system. Measurement results on the human body show that the proposed SoC can effectively acquire ECG signals.

Low-power low-data-loss bio-signal acquisition system for intelligent electrocardiogram detection

“…As society progresses, high demands for the quality of life increases. Smart wearable devices with good and stable performance and low power consumption have recently been developed [5], and low power consumption has been a significant feature of the wearable devices. The MPU MSP430X, because of its low power feature, was selected for the proposed design.…”
